Make it a proper class:
public class LabelWithDefaultText extends Label {
private String defaultText;
public LabelWithDefaultText(String id, IModel model, String defaultText
) {
super(id, model);
this.defaultText = defaultText;
}
@Override
protected void onComponentTagBody(MarkupStream markupStream,
ComponentTag openTag) {
String model = (String) getModelObject();
replaceComponentTagBody(markupStream, openTag, model == null ?
defaultText : model);
}
});
}
Or make a model wrapper
